Extreme Dinosaurs

65 million years ago, dinosaurs ruled the Earth. Yager arrived on Earth during this period in his time-space spacecraft, capturing the Stegosaurus, Tyrannosaurus, Pteranodon, and Triceratops for scientific experiments, intending to develop biological weapons. Space police officer Sanna had been tracking Yager for a long time and also traveled to ancient Earth. With Sanna's help, the dinosaurs successfully broke free from his control.
